CU-LTIVATOR.

SPECIFICATION forming part of Letters Patent No. 283,910, dated August 28V, 1883.

` Application inea May I, Issa. (No model.)

To all whom it 11m/y concern,.-

Be it known that I, MARION WV. MCCANN, of Posey township, (Dublin, Wayne county, P. 0.,) county of Fayette, and State of Indiana, have invented certain new and useful Improvements in Cultivators, of which the following is a speciiication.

My said invention principally consists in an improved means of attaching the plowsof that class of cultivators having arched axles to said axles, whereby said plows are adapted to be moved nearer to each other than when only the ordinary Ineans of attachment are provided, as will be hereinafter more particularly described.

It further consists in an improved means of attaching the animals to the plows.

Referring to the accompanying drawings, which are made a part hereof, and on which similar letters of reference indicate similar parts, Figure 1- is a top or plan view of a cultivator embodying my said invention, a second positionof the plows and the means of attaching the same to the axle being shown by dotted lines 5 Fig. 2, 'a central vertical section of the same on the dotted line z z; Fig. 3, a view looking to the right from the dotted line y y,- Fig. 4, aview looking tothe left from the dotted line Fig. 5, a detail, sectional View, looking upwardly from the dotted line w w, on an enlarged scale; and Fig. 6, a detail horizontal section on the dotted line c o.

In said drawings the portions marked A rep resent the arched axle; B, extension-pieces secured thereto, to which the plows are attached 5 C, clips by which said pieces are secured to the axle; D, the plow-clevises, E, the plow-V beams; F, the pole, and G a curved bar, to which the single-trees Inay be attached.

The axle A is' an ordinary arched axle, and is mounted' on the usual wheels, A..

The extension-pieces B are rectangular or link-shaped devices, upon one end of each of which is formed a collar, b, by means of which, in connection with the clips C, it is attached to and adapted to slide upon the horizontal portion of the axle between the arch and wheel.

One side of this extension-piece serves as al bearing upon" which the box for the plowclevis slides, and the other as the means whereby the device is rigidly secured in any desired position on the axle.

double-tree, F.

portions of the extension-pieces which are beside them. When it is desired to change the position of said extension-pieces, it is done by simply loosening the nuts c upon the bolts c', thus releasing the hold of said clip upon said extension-pieces and permitting them to be moved along the axle to the desired position. After this is done, by turning the nuts in the opposite direction they are again rigidly secured to the axle.

The clevisesD are ordinary clevises, which pass around the boxes d, and to which theplow-beams E are preferably fastened by means of the pivot-bolts e. thereon, are secured in any desired position on the extension-pieces by means of set-screws d.

The plows E are attached to and slide upon the extension-pieces B, and are adapted to be adjusted to any position between the two extremes shown by the full lines and the dotted lines in Fig. l. As will .be readily seen, this limit of adjustment is practically the same as ifa straight instead of an arched axle were employed, and thus my invention combines the advantages of both forms of axle.

The tongue F bears the usual cross-bar o ,r

These parts are of the ordinary construction and need no special description.

The curved bar Gis provided at convenient intervals with holes g, whereby the single-trees are secured at any desired height yfrom the ground. These bars are secured at the top to the ends of the double-tree F', preferably by means of staples f, and at the lowerA end they are connected to the axle by the rod G and clip g. l

My invention is operated as follows: The extension-pieces are moved to any desired position upon the axle A, and then are secured in that position by tightening the nuts on the bolts of the axle-clip C. The boxes d, witlrthe plow-beams attached thereto Vby means of the clevises D, are then placed in position on the extension-pieces B and secured in place by the set-screws d. Thus, as will be readily seen,

the gangs of plows may be placed in any positions from side by side of each other in the center of the axle, as shown by the full lines in Fig. 1, to positions at the extreme ends of the axle, as indicated by the dotted lines. This The axle-clips C encircle the axle and those The boxes, with clevises IOC ` axle in a single implement.

Having' thus fully described my said invention, what I claim as new, and desire to secure by Letters Patent, is-

1. In an arched-axle cultivator, the combi nation, with said axle, of the extension-pieces B, secured thereto by means of the collar-like ends b, provided on the ends next to the ends of the axle, whereby said extension-pieces are adapted to slide upon said axle and extend l nearly their whole length beyond. the upright part of the axle, thus practically forming a straight axle, substantially as set forth.

`2. In a eultivator, the combination of the arched axle,l the link-shaped extension-pieces B, and the plows, one side of said-extensionpieces being secured to and adapted to slide upon the horizontal portions of said axle, and

said plows being securedl to and adapted to slide upon the other side of said extensionpieces, substantially asset forth.

3. The combination, in a cultivator, of the arched axle A, the sliding extension-pieces B, securedthereto by collar-like ends b and axleclips C, and the plows E, secured to said ex tension-pieces by the clevises D and pivot-bolts e, substantially as set forth.

In witness whereof I have hereunto set niy hand and seal, at Indianapolis, Indiana, this 4o 26th day of April, -A. D. 1883. l
